Baby went back to waking every 2-3 hours 😭

Sonia

My baby had been doing 5-6 hours stretches over night for about 2 weeks and suddenly the day she turned 12 weeks she regressed back to waking every 2-3 hours.

I really don’t want to give her bad sleep associations but the only way she’ll go back down is by breastfeeding. I feel like I’m starting a habit that I’m not going to be able to break 😭

Does any one have any advice as to how to get her to sleep longer stretches again ?
